It is adviced to take offline every non-vital services until the patch has been installed (or the Docker image has been updated with a patched version of PHP)

“I felt a great disturbance in the Force, as if millions of Wordpress sites suddenly cried out in terror and were suddenly silenced.”
Seriously though, how quickly do you expect patches to be available for WordPress? I’ve got one WordPress site that I made years ago for a friend’s business. I pop in on it and update stuff every few months.
Should I take it down?
it’s PHP that needs the patches. Yes you should take the site down until PHP has been patched.
edit: assuming you are hosting wordpress yourself. if you’re using a large 3rd party service that manages PHP itself like wordpress themselves, one should hope that they will be updating PHP early, before the patch is even released publicly.
Yeah it’s self hosted, thanks
it’s a lot more than wordpress…
